I've learned vim in the standard vim editor at the time, so I can only guess but it should probably work. 99% of my work with vim is navigating and editing text. The rest is macros and substitute, all of which is available in IntelliJ. The things you miss out on are (I think) colorschemes and vim specific plugins (which you mostly don't need because you have a fully fledged IDE).
