Is it possible to change the name of a partition and icon?

Click with your right mouse button, show info. Change the name. Look up the picture you want instead of the picture it now has (google a nice picture or take the picture of another folder/partition), copy it with right mouse or "command" "c". Go to the info window of the bootcamp partition. At the top of the window should be the picture you see in finder. Click it and press "command" "v".

I did this to change my TimeMachine picture. I didn't want it to have the TimeMachine picture, but the normal one. So I copied a picture from another external hard drive.

 

You can rename a partition by selecting it in Finder, pressing return, and typing the new name. However, I've had to rename my Windows partitions from Windows. I can't remember exactly how it's done, but I think you select the partition, right-click, and select Properties. It should be somewhere under there.
