Can I drive with the check engine light on if it's only for AC compressor?

What is your question?

2010 Toyota Prius High pitched buzzing sound on the passenger side, only makes the sound when the AC is turned on. Check engine light comes on and stays on as soon as the car is started. Can I drive the car safely and without any other damage to the car until I can get it fixed?

What makes this problem better or worse?

The noise stays the same as long as the AC is on

How long has your 2010 Toyota Prius had this problem?

I've heard the noise intermittently for about 6 months but now it's constant and the check engine light came on yesterday
