I can't see why not, especially if you have the same question that they did.
If you don't, I recommend possibly giving the people who asked them initially the opportunity to do so first by waiting a few days at least, particularly if you have no subject knowledge yourself. We want to be certain to get a good base of users with some starting rep so I don't think we should make an effort to "force add" the questions from commitment phase, particularly as it can make whoever does it look a bit rep-hungry.
For example, if I think a question about woodcutting is really good but I have no actual interest in the subject, I will have difficulty actually formulating a good body to the question, so it doesn't make sense for me to ask the question myself.
However, if there's a question about crocheting that I've always had and I want to take the time to write a good question about it here, it completely makes sense for me to ask it, regardless of who asked it in commitment phase.
