Wordings such as "is it safe" are not too good, you may want to specify what's "safe" for you. As it stands, one could very well answer "Yes, sure" as it is perfectly safe to delete this folder. Only just, uninstalling some software (if that is needed) gets a bit tedious later. Updating, surprisingly, works fine for most programs, TortoiseSVN being one notable exception (ask how I know). If "WTF, I'll just delete stuff manually" which includes deleting a few reg keys is a workable approach for you, then there's absolutely no problem.

According to Microsoft employee joscon in the Microsoft Technet post "Can you safely delete files in the %windir%Installer directory?", it is not safe to delete C:windowsinstall or any files within it, and the post explains why as well.
I've referenced and quoted the portions of the post that relate to your question and helped make it more clear and concise for the specific subject matter of your inquiry.
Can you safely delete files in the
%windir%Installerdirectory?
The answer is flatly: "No".
Let's talk about why this is a bad idea:
First, it is not supported. If you remove files from this directory
and have issues, you may need to reinstall the application to get
back to a good state.
This particular directory's job is to act as a cache location for Windows installer based applications. It holds stripped down versions
of the Windows installer data files. During application install,
update of the application or application removal, this directory is
used by the application to confirm the existence of previously
installed items to determine the next steps the installer needs to
take.
- The files are different from machine to machine, so if you
expect to delete the files in the directory and then copy them over
from another machine, that would be incorrect. Removing items from
here could cause you to have application crashes, or worse, require
the re-installation and patching of the application.
The overall idea that you really should not remove items in the
Windows directory. We build and test our software based on the
existence of specific files and directories. When those files and
directories don't exist, bad things can and will happen. However, that
is a generalization that usually upsets many people so let's be more
specific.
The proper way to alleviate space pressure in this directory is to uninstall any unneeded applications.

More specifically, deleting these files could make it impossible to later update/uninstall some applications. Been there, done that, would not recommend.

The C:WindowsInstaller folder is where some but not all applications uninstall files and folders are stored.
If you want to remove applications, use the Control Panel Programs and Features to uninstall them. It is also possible to run Disk Cleanup (cleanmgr.exe) in elevated mode to help free up space.

Wordings such as "is it safe" are not too good, you may want to specify what's "safe" for you. As it stands, one could very well answer "Yes, sure" as it is perfectly safe to delete this folder. Only just, uninstalling some software (if that is needed) gets a bit tedious later. Updating, surprisingly, works fine for most programs, TortoiseSVN being one notable exception (ask how I know). If "WTF, I'll just delete stuff manually" which includes deleting a few reg keys is a workable approach for you, then there's absolutely no problem.

@PimpJuiceIT, your answer is great, as usual. Obviously, I was the person who edited the canonical question tags, because when you cut through our mildly subjective interpretations it essentially is the same question, regardless of the specific OS version. In fairness, even your very high-quality answer is based upon a TechNet blog from 2012, which easily predates the existence of Windows 10.
