Yes, there is a facility to do so in ISID, I did it for an accidental oil service entry, it doesn't work for all CBS items though, for example the brake pad change (I don't know why).

There are further options and probably possible through the use of Tool32 but I haven't used this on an F Series car, it's just something that I have come across during a bit of research.

You also cannot undo an accidental battery registration using the dealer software, I'm not sure if other factory software can undo it. My gut feel is that it wouldn't be possible.
