Special relativity says it's not possible. General relativity says that maybe you can get something equivalent by taking non-linear paths through space-time but those sorts of things require very radical types of matter to avoid collapsing into a black hole. And realistically, it's IMO very unlikely that these sorts of things would remain in a more complete (e.g. quantum) theory of gravity.
