This is because there's no expansion since pressure and volume are constant, right?

Yes, I believe that if the system is under both constant V and P (however, I think there will only be questions with one or the other) the change in internal energy will equal the change in enthalpy. And since P and V don't change, there is no expansion. However, there are cases when P and V are constant and the system still expands (like in a vacuum).
