As names of political movements or affiliations, they are usually interchangeable in the sense that what is true of "corvids" is usually true of "jackdaws". Not always, and circumstances might make just one the relevant term to talk about, but in common usage it's just being annoying to police the use of the word "socialist" when the person in question is a communist (and therefore also a socialist).
I'd never police someone about that. But sometimes it is really confusing trying to get what someone is saying if they switch the terms around all the time.
