What sort of damp is this?

Condensation behind furniture is very common, as it blocks heat so, if external, that part of the wall is colder, so condensation forms on it.
If the wall is damp, the furniture impedes air circulation so it does not evaporate off the wall and into the room. To my eye it looks more like a damp wall. The foil test will tell you which it is (might be both)
Mould spores are everywhere in the world, all the time, and will grow if moisture and temperature are suitable, so concentrate on getting the water down.

No it's an internal wall and I'm reasonably sure it's a stud wall.
My wife says the walls still feel damp. Oddly there is no mould on our walls shared with neighbours even where there is furniture against the wall. The only difference is these walls are brick whereas internal walls are concrete blocks or partitions. Though the external wall is of course brick.

Any moisture in that, which might have leaked? There must be a source for the water..
None at all, it's not connected to anything.
Can you even get rising damp in hollow stud walls?

No, the relevant difference is that they are not cold external walls. On the other side is an enclosed space which is most likely heated.
Cold external walls are prone to condensation. Warm internal walls are not.
To do that I assume you have to make sure no air can get underneath?
Today my wife noticed salty looking tide marks in the walk in cupboard, then went under the stairs to retrieve Christmas items and there was a dripping leak from the piping there. This meant the concrete floor is wet. Could that have then run in to the underlay under our laminate would affect flooring wet and travelled several metres to the wall and caused the problem?
Yes, easily!
Drying wet clothes indoors should be avoided. This is easy to address. Does the washing machine have a fast spin (1600 rpm) and are you using it? Have you considered buying a condenser tumble drier? These do not need to be vented to the outside; the water collects in a container that can be emptied down a basin; however, they need to be situated in a well ventilated room and the lint filter must be cleaned after every use.
I think that the "salty looking tide marks" are called "efflorescence".
