A dirty workaround could be to truncate each file in one of the images;
the result will be that the hardlinked files in the other images are
also truncated and hence don't take up any space anymore.
A cleaner way is indeed to remove each copy of that tree individually:

I'd do:
rm -r */tree/path/to/evil/data
or, if that gives "argument list too long":
echo */tree/path/to/evil/data | xargs rm -r
