This came up here recently, and the answer is a big resounding "NO!". A node cannot be a member of more than one cluster. The closest you get is if your cluster nodes are virtualized, so you can run multiple VMs on one physical server. Each virtual machine can only be a member of one cluster, but there can be multiple virtual machines, each a member of a different cluster, on the same physical machine.
