Yes you can.  I've done it.

Darn! Wish I had my notes with me.

I can't remember what the TIC line is all about.  I do remember that I
did not have to worry about it.

On my supply, there were several identical connectors (all with 4 pins).
Additionally, there was one long connector which normally went to the 
mother board of the pc.  This connector was the one with the "TIC" line.

I am presently running an Amiga 500 with A501, external floppy, 
two (2) Seagate ST238R HD's, Omti controller, and interface between
the A500 and the controller off this single supply, and it doesn't even
get warm.  

It is NOT a stock AT supply.  It's from some mail-order company.

When I was playing around with the hookup, I learned that it has internal
"sensing" of the load (which, in my opinion is not exactly efficient...
the load should be "sensed" AT THE LOAD).  However, it regulates very nicely
and I'm quite happy with it.
