No. A triangular pyramid describes a triangle whose base is a triangle (not just the sides which define it as a pyramid), whereas a rectangular pyramid is one whose base is a rectangle. A triangle and a rectangle are not the same (a triangle is not a rectangle, and a rectangle is not a triangle), so it would be incorrect to refer to a triangle-based pyramid as a rectangle pyramid.
