What's the acid test that qualifies startups as lean or not-lean? I think lean startup advocates would argue that lots of household names (google, facebook, youtube, etc) utilized lean methods, even if they weren't consciously doing so. Not sure if I'd agree with them, but they probably would say that. Consciously promoting lean startup ideals != doing things the lean way. The lean startup movement is more about a label and a tribe than it is a set of behaviors (not that this is necessarily a bad thing).
