If you wish to, you can draw a simplified MO diagram showing stabilization due to overlap of the $\ce{B}$ $2p$ and $\ce{F}$ $2p$ orbitals, but the valence bond theory argument suffices. When B F 3 changes to B F 4 … In B F 3 molecule, B − F bond has partial double bond due to presence of p π − p π backbonding between B and F, which removes the electron deficienty of the molecule.
