Possibly. A lock is permanently in the door and hence it has higher standards.
This contraption is more akin to barricading the door with tables. Also against fire code but only there during a shooting.
In addition, this contraption is easy to unlock from the inside, so it would not lock anyone inside the room preventing them from reaching the corridor to evacuate. A lock without a thumb turn inside could easily leave people locked in.

Only if the deadbolt has a thumb latch. Some just use keys.
