Kind of. It can be done with git-read-tree. I.e.:

 $ git-read-tree --index-output=.git/tmp-index <branch-name> && \
    mv tmp-index .git/index && \
    git update-ref HEAD <branch-name>

This does not appear to do what you think it will.  git update-ref
will write the SHA1 of <branch-name> into the current HEAD, not
switch HEAD to a new branch.

ach, right. Dangerous: it can change the ref HEAD points to. Very sorry!
Better just:

 $ rm .git/HEAD && git symbolic-ref HEAD "refs/heads/<branch-name>"

In the end, you just have git-checkout minus git-checkout-index. Maybe
a "git-checkout -n" can be useful. Even though I can't imagine what for.
