You shouldn't have any problem with even taking a few cm off the length. What the line is compensating for is hardly precise and the line is made long enough to give plenty of margin for triggering speed.

HP scopes used two zig-zag tracks on a very long piece of very thin PCB. screening foils were added and the PCB rolled-up! Some added inductance from coiling the inners of twinax like line, or by increasing dielectric constant slows the line down so less length is needed. Good matching is needed to avoid mutilating waveforms.
