If you mean the GPS location, then yes, you can fake that (look at the very bottom of the page):
Android DDMS
Using the DDMS, you can simply tell your device its current GPS coordinates.
EDIT: I guess, this post answers your question Stackoverflow. It points out that SensorSimulator is capable of doing that. If you scroll down a little bit on the page, it explains you how to connect the tool with a real device. I myself have never used it, so just try it :)
Hope it helps!
