can we associate CCM and DNG team's?

The question is not any better. It is unclear to me what associate means and what the purpose of the association would be. Anyway, the answer is most likely: No

 I'm going to guess that you are asking whether a CCM team area can somehow be associated with a DNG team area, similar to the way one can associate a CCM project area with a DNG project area, using the Lifecycle Project Administration application, and that the purpose of the association is to somehow simplify adding team members to both of those team areas.  Assuming that is the case, then Ralph's answer applies, i.e. "No".
