Installing SharePoint 2010 Beta on Windows 7 or Windows Vista

It is indeed possible! Microsoft has a good set of instructions here:

Note that the step where you copy the long Windows command needs to be concatenated to one single line. I copied the text to Notepad, then pulled things back to a single line & it worked fine.

Enjoy!
