V1
It's a great question and needs to be better explained.
In theory (and it's just that because no one has a conveyer belt wide enough)
Yes.
The problem is with Accelerate/Stop distances. Should an engine fall below V1 the length of conveyor belt required to bring the aircraft to a halt will be greater than the length of the belt itself, and will result in an overrun.
As an aside, an Airbus won't takeoff, due to Control Law protections. They've tried to make them idiot proof...
