You can, but you can only be logged into one account at a time on the iPad, an email address can only be used on one account, and content is tied to the account that originally bought/downloaded it, and using iTunes Match, turning on automatic downloads or re-downloading past purchases could tie the iPad to an account for 90 days (http://support.apple.com/kb/HT4627) - it's usually best to have and use just the one account
