Interesting, that's the first dictionary i've ever seen that lists it - Merriam-Webster, Cambridge and Websters all claim it's not a word. (As well as google - "Did you mean: minimalist")
In any case, all three are adjectives with what appear to be interchangeable meanings, so using the shortest suitable word seems most in the spirit of minimalism.
