Of course. Use complete-word instead of expand-or-complete:

bindkey '^I' complete-word

It will totally ignore any patterns and try to complete "as is". But 
note that new completion gives you choices between completion, matching 
and expansion and you can select the order in whch it happens and and 
and ...

If it is the sole reason to use prefix completion - my example does it 
as well. It does better job than bash - it checks suffix as well and 
won't try to complete prefix if the whole completion would fail. Wit zsh 
you can do:

cd /u/bTAB
It completes to /usr/bin - you realise you made a mistake. Press Undo 
(^_ or ^Xu by default). You get inital line. Go back, add `l/' like in

cd /u/l/TABb

and it will be completed to /usr/local/bin. But *only* if /usr/local/bin 
exists. And it will move cursor to the end if you have the single choice 
or to the first ambiguous place if you have multiple choices. And this 
is configurable as well :-)

You have to use expand-or-complete-prefix instead of expand-or-complete 
(or complete-word), like

bindkey '^I' expand-or-complete-prefix
setopt completeinword

But then your first problem is back - there is no complete-prefix widget.
  It is unlikely that any will be added - new completion can do 
everything you want and with much better configuration possibilities. 
(modulo bugs, as looks there are with menu and list styles)
