It has been found that the contrary is more likely, i.e. putting AdSense (specially if you have too many ad units per page) lowers your chances to some degree for some webmasters to link to your site, thus making it harder for those sites to improve in ranking.
Aside from that, I believe that most webmaster are fairly convinced that using AdSense does not cause an intentional change in your Google ranking. I'm not as willing to bet on your MS ranking.
