Yes, there is some overall resemblance.It resembles the Saab 35 Draken.
But the air intake system, the cockpit, the fuselage airfoil design, the vertical stabilizer, dorsal fin, the frontal aspect cross section, etc, are all different.
And that's easy to understand. The 35 Draken was a aircraft that first flew in the 60s. The F-16XL first flew in 82.
Good comparison here:
