Hypothetical question... Say your adsense account got banned for either ad misplacement, click fraud or copyright.. Will your site be De-indexed from google that was registred with that Banned account?
Nope.. Google Indexing and Adsense are totally different. But, both could happen in same time if the site in question breaks the rules for both. (Like, Warez content, illegal drugs etc)
Simple answer - No. This could apply to another similar case like - If your website got de-indexed it will not effect your Google Adsense or Adword account anyway. Google does always treated each case separately.
Google indexing is for their search engine results, so they wont be de-indexing your account in case your associated adsense account has been disabled or banned.
