Yes you can. We need to look at two Group Policy objects for this question. Both can be found at Computer Configuration à Policies à Administrative Templates à Windows Components à Internet Explorer à Compatibility View. The first one I want to point out is Include updated Web site lists from Microsoft. This setting will allow the use of a website compatibility list that is maintained by Microsoft. It is updated through Microsoft Update.
The second policy we need to look at is Use Policy List of Internet Explorer 7 Sites. With this setting enabled, you will be able to add specific sites that will run in Compatibility Mode for your users. Your users will still be able to add and remove sites on your own. They will not be able to remove sites that you specify.
