I don't believe so. Not without an extended license:
In the new “MICROSOFT SOFTWARE LICENSE TERMS” for Windows Vista, “Section 2:
Installation and Use Rights” reads:Before you use the software under a
license, you must assign that license to one device (physical hardware
system). That device is the “licensed device.” … You may install one copy of
the software on the licensed device.Also, Sections 15 “Reassign to Another
Device” and 16 “Transfer to a Third Party” are new, basically stating that
you can “reassign the license to another device one time” or “make a one time
transfer of the software, and this agreement, directly to a third party.
