Faster than the speed of light? Probably not.
Considering the age of the universe, it would be a more probable assumption that if it was a live form, it has a life duration much much longer than ours and thus could tolerate an extremely long trip.
It's very doubtful that the laws of physics will be exceeded. Variances in a physical body are much more realistic.
Why do we measure speeds of travel in the universe with the speed of light? Because it is the fastest thing we know about. The key word here is WE. WE can't figure out how to get humans to Mars safely yet so why would you assume this being is capable of living extremely long, yet not have more advanced, and closer to the truth, laws of physics? You can't debunk an assumption using another assumption. If they are more advanced in one way, they can be just as advanced in another.
