Computers and radios have an uneasy coexistence.  I have had problems
of mutual interference at home between a PC and my ham radio gear.
Most of the time, problems are minor (slight interference with radio
reception mostly), but on some bands my shortwave transmitter causes
the PC to act like someone is leaning on the keyboard.  They do share
a power circuit and cables from both share a rats nets of wires behind
my desk.  Problems will vary with distance, orientation, power levels
and operating frequency (since some poorly shielded wire in the
computer could resonate and absorb a lot of energy).  Some hams have
had problems with transmitters confusing the new computerized cars.

I would certainly avoid trying novel combinations of gear during
important computer activities.  Since power falls off rapidly with
distance, you can also move away before transmitting to reduce risks.
