Yes.  But you'll have to change the binding for each mode you use:

(add-hook 'lisp-mode-hook
          (lambda () (local-set-key (kbd "TAB") 'end-of-line)))

You might be able to fudge it by using key-translation-map to generate a
user-defined function key from (kbd "TAB") that you would map globally to
end-of-line.
