yes it is; there is not much to quote as the Code does not require a dedicated circuit for a refrigerator.
If you look at this in reverse: 210.52(B)(1) - says the 2 small-appliance branch circuits shall serve all the countertop receptacles required in 210.52(C)(1) AND receptacle outlets for refrigeration equipment. [Obviously the circuit load restrictions in 220 would apply].
