How do you know it is moving? There is nothing to measure against. For all intents and purposes, it could just as easily be stationary.
There are now two photons in this void. the distance between them does not change. Are they moving?
I see. Thank you for clearing that up.
As for your second question: No. I don't think so. -- How could they be moving since the distance between them doesn't change and there's no third (moving) object to compare their potential movement against?
But here's where you muddied the waters. I didn't presuppose that we are talking about a completely empty universe, for all intents and purposes. You didn't specify that. If that's the case, and there are just these two photons in this emply world then how come the observer? Where does he come in? Is it truly a void if there's someone to observe it? How do you observe this information without light? Wouldn't light pass through this void, therefore "contaminating" it and possibly changing the stationary pose of the two photons?
