The sticker in my door also only refers to 19" wheels.

I wondered if the TPMS would send a warning if it thought you'd overinflated the tires but a quick check of the owners manual says it wouldn't. It only sends a signal if your tire is low (3-6 psi below recommended) or if it detects a tire is flat. So adding extra air wouldn't bother it.

BTW...
Why don't you want to keep the 19s on? They look great on your car.
