In principle, yes.  But the way Chicken treats the stack would make it
very hard to port to a multistack design: the stack grows steadily as
different procedures are invoked, and then is popped all at once by the
garbage collector, so the C stack is the nursery of the Scheme heap.

Big as a house, much bigger than a house, it looked to [Sam], a grey-clad
moving hill.  Fear and wonder, maybe, enlarged him in the hobbit's eyes,
but the Mumak of Harad was indeed a beast of vast bulk, and the like of him
does not walk now in Middle-earth; his kin that live still in latter days are
but memories of his girth and his majesty.  --"Of Herbs and Stewed Rabbit"
