It seems not. I've looked up a few old-fashioned algebra books which
might have used such a name. Hall & Knight "Elementary Algebra for
Schools," 7th edition (1897), p.332, just says:
"The expansion of a binomial may always be made to depend upon the case
in which the first term is unity; thus
(x + y)^n = (x(1 + y/x))^n = (x^n)((1 + z)^n), where z = y/x."

That's the sort of thing I remember seeing in other old algebra books
as well.
