Can I connect FEX ports on the 2K across multiple VDC's on the 7K and enable the 2K to support multiple VDC's?

Guidelines and Limitations for the Fabric Extender

The Cisco Nexus 2000 Series Fabric Extender (FEX) has the following configuration guidelines and limitations:

Beginning with Cisco NX-OS Release 5.2(1), the default port mode is Layer 3. Before Cisco NX-OS Release 5.2(1), the default port mode was Layer 2.
You must enable the Fabric Extender feature set in the default virtual device context (VDC). After you enable the feature set in the default VDC, the FEX can belong to any VDC and can be configured from those VDCs.
All the uplinks and host ports of a Fabric Extender belong to a single VDC. The ports cannot be allocated or split among multiple VDCs.
