| B15M,
I always find it easier to understand concepts when I take them to Nth degrees in both directions. In this case, imagine that you took your slide out as far as it could go without it falling out. Sure, you could play it but think about the ramifications aside from the flatness of the intonation:
if you pull the slide all the way out the horn plays oddly and the notes are tubby and uncentered. When you pull the tuning slide out, wouldn't you also have to pull the other slides out in order to bring them into balance with the tuning slide? Of course. You would also have to play a mouthpiece that is the proper length, as well. In this case it would have to be longer like a conventional mouthpiece, since you play a Monette B15M normally.
So, there has to be an optimal place for the slide to be that brings it into balance with the rest of the horn. My Bb tuning slide is out further than my C trumpet slide just for example and my C mouthpiece is shorter than my Bb piece.
