On the Windows server, you probably can, but the linux platform, it's probably not supported by TAC. The Root access to any of the linux platforms is locked down, hence, you cant install additional components. I'm not sure what a third NIC would do for you since (2) are on board and configured for Fault Tolerant. Plus you have iLO to access the box if something was down between the NICs.

The reason being, (2) NICs on each server for CUCM, there is always another Subscriber or backup CUCM server in the cluster to take over. Segmenting out network appropiately and designing the infrastructure appropriately will take care of adding in a third NIC for you.

For an official answer, check with TAC, but we can all assume it's a no.
