Entity A and Entity B are strong entities and they have their own identifiers. Their Many-to-Many relationship is resolved with Associative Entity C, which has its own Identifier. I am just wondering if Entity C can have another relationship with a Weak Entity D whose existence depended on the Associative Entity C identifier.

Yes it can. You can find this in Fundamentals of Database Systems chapter: "Entity Relationship Extended" (I have the Spanish version so I'm not really sure about the exact translation)
