Tough question. I would say, ordinarily, no. The reason is that ordinary light beams can't be thought of as collections of individual photons. In fact, they aren't even close to having a definite number of photons in them.
There are special sources in which nearly definite numbers of photons (e.g. one) are emitted. In those cases, if the light bounces off some surface, I think it would make sense to say that the same photon that bounced was later seen.
