Yes and no.

If a list is included in the BCC: field and the 
require_explicit_destination setting is on, this will work for BCC: 
That setting is located on the Privacy Options->Recipient Filters page.

It will not work for CC: as mailman basically treats the TO: and CC: 
fields as essentially the same thing (which is in accord with the 
applicable RFCs). In order for this behavior to be different you will 
either have to modify mailman code, use a custom handler in the 
incoming stream or filter such messages at the incoming queue of your MTA.
