magnetron for the transmitter. We were wondering if this would be
legal.

No, it would not be legal to do it as you described. However, there
are lots of ways to do it legally:

And why not in the USA?

Microwave oven mangetrons operate at 2.45 GHz, which is the top of the
2.39 to 2.45 GHz band and should be trivial to pull down a little bit.

All modes are allowed in the band.

All licencess other than Novice can use the band.

Microwave magnetrons would likely have unacceptable spurs and sidelobes,
as the frequency is not very stable.
