Depends on the exact definitions. 'dynamic loading' (whic I would define as with ::LoadLibrary() ), is a subset of 'dynamic linking' because dynamic linking can be done explicitly (with ::LoadLibrary()) or implicitly by the application's startup code, which is generated/inserted into the executable by the linker.
Then again I wouldn't have a problem with someone defining the terms differently so that they are the same or overlap in a different way. I wouldn't say though that they are very different - they are related no matter how you slice it.
