No, you can’t mix full and server core installations in one cluster. If you run the Validate a Configuration action from the Microsoft Management Console (MMC) Failover Cluster Management snap-in, it will fail the Validate Operating System Versions check. The action’s report will state that you cannot mix full and core installations, as the following screen.
