I can't reproduce it.  I did:
emacs -Q
(require-theme 'leuven-theme)
M-x enable-theme
TAB

And "leuven" was inserted at the minibuffer.

I tried on Emacs 28, Emacs 29 and master.

It should offer the completion, and at least it does for me. What were
the steps that you followed? And on which Emacs version?
