I tried this in *scratch* and it works fine:

(defun test-kill-buffer (fname)
  (find-file fname)
  (kill-buffer))
C-x C-e
(test-kill-buffer "/tmp/abc.txt")
C-x C-e

Repeat the steps and leave out the "(kill-buffer)" and the file
/tmp/abc.txt remains in emacs.

So it must be something with (funcall exp-function) or exp-function,
which prevents unloading `fname'.

Maybe org-export-as-html-and-open changes buffers. So, I guess either a
save-excursion around (funcall ...) or:

(defun test-kill-buffer (fname exp-function)
  (let ((buf (find-file fname)))
    (funcall exp-function)
    (kill-buffer buf)))

(test-kill-buffer "/tmp/abc.txt" 'some-function-to-call)

will do the trick.
