Sure. None of those organisations have power over you (unless you work for them, I guess). You’re free to use whatever name you like for whatever you want. Whichever organisation names venomous snakes has no power over you either, but if you’re bitten by one and they ask you which one it was so they can administer an antidote, I highly recommend you stay with the name they gave it instead of some other name you made up. You do you, though, don’t let me stop you.
