2) They certainly have the right to.
I suggest that you read Google's "Terms & Conditions" and "Program Policies" immediately.
For example, if you use affiliate link exchange programs like Commission Junction, they have a number of banner links that are designed to look exactly like text ads.
At first glance, you would never be able to tell that it's a banner and not a true text-ad.
Either way, Google would not allow this.
Competitive Ads and Services
We do not permit Google ads or search boxes accessing Google search services to be published on web pages that also contain what could be considered competing ads or services. If you have elected to receive contextually-targeted Google ads, this would include all other contextually-targeted ads or links on the same page as Google ads. This would also include ads throughout the site that mimic Google ads or otherwise appear to be associated with Google on your site. Although you may sell ads directly on your site, it is your responsibility to ensure these ads do not mimic Google ads. If you have elected to receive Google search services, this would include other search services on the same site and non-Google query-targeted ads. We do allow affiliate or limited-text links.
Outside of that, a paraphrase of David_UK's message from Google Adsense:
This would also include ads throughout the site that mimic Google ads or otherwise appear to be associated with Google on your site. Although you may sell ads directly on your site, it is your responsibility to ensure these ads do not mimic Google ads.
Notice Google used the term site and not page, which means they do not allow mimicking Google ads on any page within the site.
I know the term, "mimic" can be tricky, since a Yahoo ad may not look exactly like a Google ad, but I would either ask Google, or not try it at all.
