control room/mix room is to be a critically accurate reproduction space that should be as neutral as possible that allows a user to make critical mixing decisions of which are not skewed or masked by how the room imposes indirect energy at the listening position.
a listening room can have a myriad of design requirements - from that mimicking a control room (eg, a critically accurate reproduction space), or a subjectively pleasing listening space based on the owner's own personal preferences. the user could decide to allow the room itself to function as an "FX", as in some home theater applications. the user could also wish for any and all source material to sound subjectively pleasing, where-as a listening room designed for accuracy with respect to the direct signal may clearly show mix/mastering flaws in the source material (eg, a poor mastering/mix job).
both may have design requirements adjusted to account for additional seating/listening positions and arrangements (listening room may have a row of seats, a control room may have a rear couch/listening position for the clients, - and also the mix board/work surface,etc).
