Yes, you can mount lead free BGA with Non-ROHS process, we call it mixed process. Our PCBA also have such situation, we increase the reflow profile about 10 degrees compare with normal Non-ROHS, to make sure peak temperature between 220~230 degrees, and perform X-ray inspection for each BGA. For the detail profile, you can check with your solder paste supplier, they should can give you some suggestions.
