In a reversible reaction, delta S of the system is equal to delta S of the surroundings because delta S of the universe is 0. But I'm pretty sure that the general equation you described in your question applies to all reactions.
That equation can be applied to any situation. It's just telling us that the entropy of the surroundings and the system can be added to get the total change in entropy of the universe. If we're considering an irreversible reaction that happens spontaneously, it will have a positive delta S of the universe.
