Nothing bad will happen! All present day receivers are well-designed and capable of handling 4 ohm speakers.

You should look up the wpc on the Arcam for a 4 ohm load vs. the 8 ohm rating. Should be 1.5x, better if 2x. Also look up the impedance for your speakers across the frequency range. Hopfully impedance doesn't drop below 3ohms amywhere.

Otherwise, and given this is an Arcam receiver, if at maximum use volume the speakers don't sound stressed the compatibility should fine.
