I believe so. Now, I can't recall what Marcus said about the torpedo's when he briefed Kirk and Spock about them in his office but if they were essentially secret equipment he may not have wanted non approved officers knowing too much about their operation. He wanted the ship to use them on a covert assassination strike in enemy territory, he didn't need the people on the ship to know their innards.
That's without being able to remember what exactly was said about them. But they were pretty much meant to be top secret tech and Scotty I think basically was not in a 'need to know' position. Despite being Chief Engineer. The secrecy around them is after all, supposedly why Carol Marcus forged her way aboard to find out what was special about them.
