Pekkle no Oni
Oni • Nonhuman • Shadowlands • Supai After the first time each turn Pekkle enters play: Gain 3 Honor. After Pekkle is destroyed: Lose 10 Honor. Political Limited: Bow Pekkle: Gain 1 Honor.
Imperial Command
Political • Imperial Reaction: After a target card is destroyed: Remove it from the game. Reaction: When an action would target your Unique Personality, pay 2 Gold: The action targets another of your Personalities instead, if legal.
My opponent destroys Pekkle, for example, with a Hired Killer. Can I react with Imperial Command for avoid the honor loss? Thanks.

No. Pekkle No Oni's trait will kick in before the Reaction can be played. Traits and Reactions are E and F on this list, respectively: http://rules.l5r.com/Timing#Resolving_timing_conflicts
