Mostly of intent -- a choke is taken to be in a low-Q circuit, a coil
may or may not be. If it's marketed as a "choke" then you don't want to
use it for tuning or impedance matching; if it's marketed as a "coil"
then inspect the specifications closely before proceeding.

And if the specification calls it a "choke coil"?

Then its part of the "early choke pull off" that was so popular in cars
in the 1970's. Its just a heater for the automatic choke thermostat.

Then they're using like a choke, and they recognize that it's a coil.
