if they're pointing the same way, yes, but if the motors are facing each other (ie nose-to-nose) they will need to rotate in opposition (ie one clockwise relative to itself, one anticlockwise relative to itself). I think this is what Dzackman meant. So you could keep the software direction the same, and just swap over a couple of wires on the motor itself.
Also make sure that when both motors are powered up their preferred positions do not "fight" with each other - that is to say, their stepped positions are co-ordinated with each other, and one isn't half a step out or anything like that.
