LDC1312-Q1: Layout Query

Part Number: LDC1312-Q1

Is it ok to make a 4 layer board, with two layers of coil, one layer for ground and one layer for LDC1312 and other components. I want to keep size of the board not more than the size of coil. Is this approach ok? Or do I have to make two separate 2 layer boards and connect the PCB inductor from one board to another using connectors?
