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:

https://www.chiark.greenend.org.uk/~sgtatham/coroutines.html

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