Manufacturers tend to say align the bung with the stem so it provides an internal stiffness to resist against the steerer tube. Having said that, I can't see how stresses generated by normal stem clamping can come close to crushing a steerer tube so I would say it's fine. But for longer time usage and to be on the safe said, worth getting a bung you can position inside the stem, or a longer one.
