Mmm, I can't seem to input C-c C-TAB either.  IIUC (but maybe I don't),
this makes sense because

- Emacs translates the function key <tab> into the control character
  TAB=^I when no modifiers are added.  I.e. this can be triggered by
  hitting <tab> or <control>+i:

> (local-set-key (kbd "TAB") (lambda () (interactive) (message "TAB-ish!")))

- But Emacs can't translate <control>+<tab> into "C-TAB", because C-TAB
  means "control+control+i", which I guess is not representable at the
  key code level or something?  Hopefully someone can explain this
  better.

(?\C-\t does return something though, and it's consistent with what (kbd
"C-TAB") returns, so I guess there's no reason why Emacs couldn't
translate C-<tab> to C-TAB like it does <tab> to TAB? 🤷)

FWIW, however you decide to fix this, I'd be very grateful if org-cycle
remained bound to TAB, since I'm one of those weirdos who actually hits
<control>+i for TAB instead of <tab>…
