in theory yes, but the switch is supplied on the downstream side of the horn relay..... this might have just been for convenience, by the designers, at the cable reel end of things, but it does add in a safety resistance/current limit for the switched supply into the cruise control.
not knowing how they set up the control board, the input voltage levels, impedance etc, i'd be inclined to replicate the original layout.
if you want to tap into the horn upstream supply, i'd fit a resistor of the same value as the resistance of the horn relay coil, just to be sure!
for the sake of 10p, i'd rather add a resistor than have to ask honda for a new cruise control computer!
