   No I don't think so.  The tail call is just a jump to that address   
   (changes the program counter).  A coroutine jump also has to change the   
   stack pointer.  See the section "Knuth's coroutines" here:

   Some Forths have a CO primitive that I think is similar.  There is   
   something like it on the Greenarrays processor.
