No, the angle of the head tubes are different on the 20 and 26 so doing this conversion isn't just a matter of slapping on a new fork and wheel. Using a 26 wheel on the front of a Giro 20 will throw off the geometry and will affect the handling of bike--most likely very negatively at that. So personally I do not recommend doing this type of conversion.
