No it wouldn't directly affect the site's rankings in Yahoo or Bing. The search engines are independent of each other, and each operates by its own rules.
However, a big loss of traffic from Google could have a long-term indirect impact in the other search engines because fewer people would see your site, and so there would be less chance of getting voluntary links from other sites.
