OK to use TV coax for microphone?

Rubbish.
Indeed. Take it out with the rest of the trash.
Good microphone and instrument cable has an insulation that drains away
static electrical charges. RF coax can contain electrical charges in the
insulation that causes it to act like condenser microphone.
Rubbish again. Where do you get this knowledge from?
Looks like a reference to some hi-Z cable that is made with condctive
fabric (or other such substance) to reduce the cable microphonic
tendencies due to the triboelectric effect of some kinds of dielectric
insulation.
