Can true damage dealt be amplified by the mastery Double-Edged Sword?

Irelia does 75 true damage with W (Hiten Style at max lvl) activated.

If I get the mastery of Double-Edged Sword, will this amplify W's true damage as well?

No.

Any form of true damage deals a fixed amount of damage that cannot be reduced or amplified. This basically means that the only way of increasing irelias True-Damage output is buying attackspeed since the damage doesn't scale with anything directly.
