I believe you are correct, you can say that rapid prototyping includes
additive and subtractive manufacturing, along with many other processes.
The term is really industry specific and all encompassing.

The way I look at it - RP (Rapid Prototyping) is what I do, AM/SM
(Additive/Subtractive Manufacturing) are the processes I use to do RP.
Then there comes the whole CAD/CNC machining, 3D Printing (SLA, FDM,
etc...) as how the AM/SM processes are accomplished. And yes there was a

thread about this a bit ago - it seemed to dissolved into a circular
discussion based on point of view :-)
