Skimming over /etc/grub.d/10-linux I see no mechanism that would limit
the number of kernels for which menu entries are created. And indeed
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/492995
suggests there is none. But this bug report has a patch attached which
implements such a feature.
If it's really that important to you that only one kernel is shown in
GRUB's menu, you could apply the patch. Ugly, but a possible solution.
