How does the Same Origin Policy apply to the following two domains?

http://server1.MyDomain.com

http://server2.MyDomain.com

Can I run JS on a page hosted on server1, if the content is retreived from server2?

edit according to Daniel's answer below, I can include scripts between different subdomains using the <script> tag, but what about asynchronous requests? What if I download a script from server2 onto the page hosted on server1. Can I use the script to communicate asynchronously with a service on server2?
