MS isn't marketing the phone to businesses. WP7 isn't shipping with support for 'enterprise' features like domain enrollment (though it does support Exchange, to some degree). Also, let's say that companies start buying WP7 phones for employees, and that they pay to build a mobile-friendly version of some internal webapp. If you were designing/coding a site today, and knew you didn't have to support IE6, you most likely code it in a fairly standards-compliant way so that it didn't break when browsers were upgraded; a lot of companies are stuck on IE6 because they didn't code their sites like that.
