If you are under IFR, ATC should take WT separation minimums into
account when vectoring you for spacing, however you remain PIC of the
aircraft and, actually, deviating from a clearance is allowed when
deemed necessary by YOU in the interests of safety. That shouldn't be
necessary though, if you feel it is cutting it too close, ask for a box
climb, or for a couple spins in a hold to let the wake dissipate.
You are PIC.
