The choice of words is here IMHO mostly a matter of framing the audience for your intentions, and possibly also whether looking at the big picture or looking at some details:

• A concept proposes a spacecraft with capabilities and possibly with a mission target or goal upon which is decided whether the spacecraft and mission is funded at all

• A scenario assumes the mission happening and outlines a particular or different courses of how the mission will be performed. This could discuss different start dates, fly-bys, different instrument utilization, possible targets-of-opportunity, etc. A scenario assumes a spacecraft with its capabilites and discusses its utilization.

Thus when suggesting a mission to a funding committee you include of course the concept with the description of the intended technology imployed, their technical readiness level (TRL) and following assumed work to be done and possibly also by whom. Additional to that you may want to include are different mission scenarios based on possibly different assumptions or timelines found in this concept.

In your particular case, you should decide whether this semantic argument is a hill to die on for you.
