Sorry for being a bit late, but along the lines of "lifting body"---almost any shape can produce lift if the angle of attack is right. (though you only get USEFUL lift if the lift/drag ratio is greater than 1:1)
Anyways, the B-1 is well-known for deriving a lot of its lift from a "non-recognized" cross section. In other words---its fuselage/gloves are not by definition aerodynamically lifting and don't conform to any standard airfoil shape---but they make lift nonetheless! Possibly the VF-25 takes that to an extreme, and manages to make a LOT of lift, enough that it doesn't need the wings, even without technically being a "lifting body" (which usually means a clearly-defined wing shape/flying wing).
