We have a treadmill so that we can exercise during the cold months in the
Northeast (current temperature is 13 degrees). The motor in the treadmill
failed and was replaced under warrantee.

The manufacturer recommends a dedicated 15 amp circuit for the treadmill.
We have it on a circuit with our TV and stereo. The technician who
replaced the motor said that it may have failed because we didn't have a
dedicated circuit. Might this be true?

I would have guessed that if the circuit was overladed the breaker would
blow.

Well... unless you had a very long circuit it would not matter. And, as
someone said, it would affect the TV more; assuming you had both on at the
same time. If you don't have the TV on, it is a dedicated circuit.

If you had a very long circuit (opposite corner of the house from the panel,
3 stories apart...) you could have had excessive voltage drop, and that
might have caused the motor to fail. It is most unlikely, but if you want
to test it, turn the treadmill on while watching the voltage with a volt
meter. If it dips significantly, you might need a heavier cable.
