Is it possible to have a calendar and reminder list with the same name?

I migrated from MobileMe to iCloud on the first day. MobileMe was then set up with my MacBook and so in iCal i saw my calendar events duplicated. I didn't like this so I tried deleting the MobileMe calendars first, then realised I couldn't delete all of them, it seemed that I must have one calendar. I then removed the the account setting (which would have been the smarter thing to do). A few hours later I notice that the calendars I deleted from MobileMe have been deleted from iCloud, as well as associated task/reminder lists. Luckily for me I made a backup before moving to iCloud so I've managed to recover my calendars.

My question is: Can I make a calendar and reminder list by the same name?

After the migration I did have some calendars and reminder lists by the same name eg. Work, Home.
