That aircraft isn't a normal 737-700. It is a BBJ with an all business-class interior. The BBJ has a higher MTOW and greater fuel capacity, which make this flight possible. Also, it doesn't in fact belong to KL, but to Privatair.

Well the range varies a lot. It can go 6,000 miles with extra auxiliary tanks. The 737-700 BBJ has the 800 wing and performance, so that means the plane can fly about 3,000 miles without weight restrictions. In the Privatair configuration, 4,500 miles is fairly reasonable. There are range charts, but they really vary because depending on the payload taken, the range can be drastically different.
The 737-700BBJ was designed to be able to fly JFK-NRT as an extreme range limit.

If you have never designed an airplane part before, let the real designers do the work!
