Yes it can. I prefer to have the fence dead parallel with the blade and the
miter gauge running parallel to the blade. Even though many like to have
the back wider than at the front on the fence side, you can still get
pinching and burning from the left side of the blade as the waste rides up
on the back side of the blade.
IMO the miter slot should be parallel to the blade and the fence should be
parallel to the slot.
