As SELinux is included in your Linux kernel, disabling it and uninstalling the userland programs is not enough. You need also to rebuild the kernel to get really rid of it. But in general I see no reason why there should be backdoors in SELinux particularly and not in other components (software or hardware).
Removing it makes your system more vulnerable against other attacks. If you have security concerns and do not like SELinux, you might be interested in others security frameworks like e.g. AppAmor or grsecurity (which seems no longer be actively developed). See for example What to use to harden Linux box? Apparmor, SELinux, grsecurity, SMACK, chroot? What to use to harden Linux box? Apparmor, SELinux, grsecurity, SMACK, chroot?.
