Should papers under review be listed in CV?
Obviously, we cannot predict how any individual committee member will react to this. However, I think it is quite common to list 'in review' papers on a CV. Two caveats:

If the number of 'in review' papers seems unusually high (compared to your past output, and submission/review rates typical for your field) people may start to wonder whether these are serious submissions, or if you've just fired off a load of half-baked stuff in order to pad your CV.
If it's on your CV, you should be prepared to talk about it during interview. Having to tell the interview panel that no, none of those papers have come out yet, in fact they've all been rejected, is not going to come across well. Personally, I would only include stuff that I'm reasonably confident will progress smoothly through the review process.
