Is it appropriate, if I defined Planck Length as the smallest distance possible for a matter to travel?

No. The PL is a combination of units, but not an absolute minimum, except in some highly speculatiove theories.

Thanks. If that so, the Planck Length is combination of which units?

Planck's constant, Newton's gravitational constant, and the speed of light.
