Absolutely!  In fact, the "ttystate" command is just a shell
script that edits /etc/inittab and runs the telinit command,
after checking that someone is not logged in on the line.
It has a few other options too.

I would be willing to post a copy to net.sources if there
is enough interest.  Although ttystate was written for
VENIX System V, it should run under any UNIX System V.
It is much easier and more reliable than enabling/disabling
login lines "by hand."
