I know that strictly speaking this isn't possible but having a look through the W7 DVD I've found that if you edit the file cversion.ini in the sources folder and change the line MinClient to the version of the RC you have installed then it will let you do an upgrade.
So what I did was copy the contents of the DVD to the local drive, edit the above file and then run setup.exe from the local drive.
No idea if this is likely to cause future problems but have just done an upgrade on my W7 RC laptop and it all went through smoothly.
