It could be possible if you fused the humanoid pelvis to the upper equine rips and the humanoid spine had major lordosis, you would probably have to add a muscle group going from the equine shoulder blades to halfway up the lumbar curve on the humanoid spine to support the humanoid portion of the centaur. This may be a viable creature, but it probably wouldn't be very functional, firstly it wouldn't be able to bend down as that motion would snap it's spine, secondly the added muscle group would be subject to constant cramping as it would be flexed constantly, lastly this design is dependent on the humanoid portion having lordosis, which is already a complication in of itself, which would doubtlessly cause further complication, that's not even mentioning the complications inherent in adding that much weight to the front of a horse's body.
