It should be ok as long as you don't play it very loud. When you run lower impedance speaker your receiver is warmer than if you run higher impedance speaker. Anyway the receiver protection will turn on when you are driving your speaker too hard so you know when to turn it down. Speaker impedance rating is a nominal value. The actual impedance fluctuates depending on frequency.
