Can an Upper with a Flash Suppressor be installed on a Bullet Button Lower?

That is the idea.
By installing a 'bullet button' or mag lock, you rifle becomes unable to accept a detachable magazine, therefore allowing you to have features that were banned under SB249. Flash hiders, adjustable stocks, pistol grips and a few others.
Make sure you use mags that are 10 rounds and under.
Run your gun through the flow chart located in the little bar at the top of this page.
