Maybe, maybe not. If there is space in the panel, you could still install a Tesla charger and go into the settings and rate limit it down to what your panel can safely provide. I installed one on my garage and moved it down from 48 amps to 40, but I am pretty sure it can go down much further if desired. Even 24 amps charges the car overnight, so it isn't a big deal at all unless you drive a ton.
