Can we please think out of the box of how you would fit that in the cfg 
file for a moment and consider the larger picture?

Yes, in that example, 'laz_svn' would be a central indirection 
identifier to your 'C:\lazarus'.
But, it could also contain protocol information (such as ftp etc.) to 
accessing a remote machine.

Because it is helpful?

But, of course, you don't have to --as long as you devise a way to get 
to the path.

How symbolic you want them would be up to you the user.

Of course you can. As long as they are identical where it matters.

I can even set up a 20 installations, even with spaces in paths. All I 
have to do is to map the root folder as another disk with a letter.

Trouble is, when I want to use another machine, I need to do pretty much 
all of it all over.

If you're so comfortable with that, then why are you interested in aliases?

Just because you have 2 file names conflicting?

You know that it's not an impossible problem, don't you?

You just rename at least them and go on living a peaceful life.

IOW, if you boil everything down to how it immediately helps you and 
only you, there's little reason to consider alternatives.
