YES   Weather beacons and APRS messages do this all the time.  (Send packets 
without position data.)

> The background on this, I have a FM-350 and a VX-8GR. Where I live APRS coverage is far from continuous. So I am often in places where the mobile can reach some distant digi, but the HT cannot. The FTM-350 does not have any digi function built-in. In order for the HT to be able to digi via the mobile I attached a TNC-X/X-Digi to the FTM-350R.

Not if it is the same radio in the same location with the same call.   (There's 
no problem with the same call in the FTM and in the Xdigi on the same radio.) 
       It's just the same as if you had both the local client function and 
digipeating enabled in UI-View or other programs.   It's just two different 
kinds of transmissions from the same station.
