Check if language is decidable

I would like to determine if the following language is decidable or not. L = { w $ \in$ $ \Sigma^*$ | $ T(M_w)$ is recognized by a Turing machine with at most 42 states}.

I know that every finite language is decidable, but I am not sure if this has anything to do with this particular problem.

Every help is appreciated, I am a little lost.

Thank you
