Is it possible to upgrade a Mac Mini to OS X Lion? I read that the upgrade to OS X Lion is not intended for Mac Minis, is this true?

Is there a way to upgrade a Mac Mini with an Intel CPU to OS X Lion?
Yes, you can update a Mac Mini to Mac OS Lion.

What you heard was incorrect, Mac Mini's are upgradable, just like any other Mac. Lion requires a Core 2 duo processor and 2 GB memory to run, so any Mac produced after circa 2007 will be fine.
