You can always ask for "Special Permission" (See 424.10, I believe it is)
Hello and welcome to the discussion. For clarity I will post the two code sections you mentioned.
424.9 General.
All fixed electric space-heating equipment shall be installed in an approved manner.
Permanently installed electric baseboard heaters equipped with factory-installed receptacle outlets, or outlets provided as a separate listed assembly, shall be permitted in lieu of a receptacle outlet(s) that is required by 210.50(B). Such receptacle outlets shall not be connected to the heater circuits.
FPN: Listed baseboard heaters include instructions that may not permit their installation below receptacle outlets.
424.10 Special Permission.
Fixed electric space-heating equipment and systems installed by methods other than covered by this article shall be permitted only by special permission.
Now to help us better understand the NEC let me post one more section of that same Article.
424.22 Overcurrent Protection.
(A) Branch-Circuit Devices. Electric space-heating equipment, other than such motor-operated equipment as required by Articles 430 and 440 to have additional overcurrent protection, shall be permitted to be protected against overcurrent where supplied by one of the branch circuits in Article 210.
Don’t know if anyone has ever seen or installed any 120 volt baseboard heaters or not but I have included them on a general branch circuit. It might also be good to know just how figuring the load for a branch circuit takes place.
220.60 Noncoincident Loads.
Where it is unlikely that two or more noncoincident loads will be in use simultaneously, it shall be permissible to use only the largest load(s) that will be used at one time for calculating the total load of a feeder or service.
Being that no one would be operating their baseboard heat and an air conditioner at the same time one can be omitted in the calculation.

Nowhere in either 210 or 424 does it forbid the installation of a 120 or 240 volt AC receptacle on the same circuit as baseboard heat. No this is not like wiring a pool pump on the same circuit as a rooftop swamp cooler either as some keep throwing out there.

Pete or Paul I would love to hear you thoughts on this.
