For normal exp cards, the only difference is the amount of exp you gain, not the benefits of leveling up. Trying to use Saber cards for a Lancer will mean you need more cards (and also spend more QP doing so), but the end result will be the same.

If you're talking about the stat-boosting cards, they can only be used on a servant of the matching class, so there's no chance of using the "wrong" card.
