No- getFontList is a built in function to actionscript, and does only that- only returns a list of fonts installed as an array. MM are very keen on Flash not having access to system level stuff, as undocumented features of Flash 5 that allowed you to write out text files to the system hd, and the FScommand functions (which worked on standalone projectors) were either removed or the way they worked changed to increase security. The only other way Flash caan access your machine is with a Shared Object- which is the Flash version of a cookie.
Heres the blurb for the getFontList from the reference manual:
