Memory manipulation is very much hacking. Pretty much the form of computer hacking.
When hacking is used in context of Gameboy games then I'd normally first think of using external tools such as a gameshark to directly edit memory, rather than game glitches. I'm not sure most people would say missingno glitch is hacking but it is a memory exploit.
