It seems not. I've looked up a few oldfashioned 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.
