yes. The issue is resource sharing as usual: the MONs will use disk I/O, memory and CPU. If the cluster is small (test?) then there's no problem in using the same disks. If the cluster starts to get bigger you may want to dedicate resources (e.g. the disk for the MONs isn't used by an OSD). If the cluster is big enough you may want to dedicate a node for being a MON.
