Yeah, depending on what signal you choose.  A signal tone could be detected
by the Teensy (there's a frequency counter library) or you could use DTMF
or the FRS radio's call/squelch signal.  But that would be hacky and
possibly not permitted by the FCC.  I'd just use radio modems if I could.

It's kind of fun to play with USB mouse/keyboard emulation on the Teensy.
Hook up 2 potentiometers and make an etch-a-sketch mouse, or have it type
sensor data in for you.  Or if you're evil, plug it in the back of
someone's PC and have it insert random keypresses or mouse actions.
