Yes. You simply make sure they are not mounted at boot. If you set them
up by adding a line to /etc/fstab reading something like:

cgroup /sys/fs/cgroup cgroup defaults 0 0

Then just remove that line, and 'sudo umount -a -t cgroup' or reboot.

If you installed cgroup-bin, then just uninstall that by doing
'sudo apt-get purge cgroup-bin'. You may after that still need to do
'sudo umount -a -t cgroup' or reboot.
