At the particle level the verb "charge" has no definition. Charge cannot be added to a particle.
A particle has charge ( noun); it is a quantum number that characterizes the particle, and its charge may be 0, +/-1/3, +/-2/3, +/-1 (and some resonances +/-2).
A photon has charge 0, spin 1 and mass 0.
That is why it is called a photon and not an electron.
If it is possible to bend it than why not charge
That it can change direction ( bend) is a kinematic effect and controlled by the equations of motion. The quantum numbers are intrinsic and unchangeable in the definition of each particle.
