Also, do ECM motors generate electrical or RF noise that is either
radiated by the motor or fed back into the household wiring, thereby
messing up AM radio reception?

Maybe, maybe not.

If you bought a commercial furnace that included one, the complete
assembly would have to comply with FCC regulations (or those of your
own national regulating body, if you're not in the US) regarding EMI
in a household environment, so you shouldn't experience any radio
interference.

On the other hand, if you just go buy some random motor that happens
to fit in your old furnace, you won't know 'til you fire it up.
