No, not directly.  That sounds like a useful feature, but Xastir doesn't
have it.

The only way to do that without hacking the source code would be to cobble
together some sort of script that reads your gpx file and creates an object
packet from it, then periodically feeds updated object packets to Xastir through
a server port.

I recall you used to have a web page called "APRS without APRS" that had
a cool script called "tracker.pl" (I still have a copy) that would construct 
object packets from user-provided position and speed information (though not 
from a GPX track), so I expect you'd have little trouble wiring something like 
that up. 

If you do that and make it general purpose enough, we could even add it to the 
Xastir scripts directory. 

(btw, the URL I have bookmarked for your old "APRS without APRS" page is no 
longer reachable, and if it's still out there at some other URL I'd be happy 
to have it.  The old URL was 
http://mckeehan.homeip.net/amateurradio/APRS/aprstracker.htm)
