Yes, but I think that's a poor choice of words; those are not the same thing. There are lots of smart people who are not independent, self-directed, or hard working! My manager was just saying to me yesterday, "we need smart people who know how to get shit done—just hiring smart people isn't enough."
They went into detail about what they were talking about, making it clear what they meant. What more do you want, new made-up words so no one can argue that this specific word has multiple definitions (as ALL words do)?
