You might be able to create a plugin using hook error_nopermission and code like:

$show['hide_adsense'] = true;

then in the template surround your adsense code with:

<if condition="!$show['hide_adsense']">
// adsense code
</if>

There might be something you could check so that you wouldn't need the plugin, but I couldn't see anything that was immediately obvious.
