In order to get an achievement from DLC, it must be earned in that DLC package's maps or a newer DLC package.

All Reach achievements for MP can be earned on all maps
Noble DLC achievements on the Noble, Defiant, and Anniversary maps
Defiant achievements on the Defiant and Anniversary maps
Anniversary achievements on Anniversary maps only.
