Yes. Research the difference between pressure ratio and absolute/relative manifold pressure. Compressor efficiency maps don't read in "boost" they read in air flow vs. pressure ratio. Exceeding the most efficient pressure ratio at a given amount of power produces excess heat and puts tress on your turbo's internals.

Edit: 17 psi up here peak, tapering to the normal 12-13 psi at redline, is probably okay. Not as efficient as that curve is at sea leel, but probably not dangerous either.
