Yes, there's nothing in SR or GR (Special and General Relativity) which prevents it from doing so. SR only prevents objects
within spacetime from moving
at the speed of light. Only force carrying particles with
no rest mass can move at the speed of light. That is photons, gluons and gravitons. W and Z bosons (the particles that mitigate the weak nuclear force) can't because they have rest masses greater than a proton.
Here's some stuff for you to read...
