I would say yes. Because replacing say a 2h 50ohm DCR choke with a 0.35uh 5 ohm choke would elevate the B+. However you have now lost a significant amount of ripple filtering with the millihenry sized choke.
So if more B+ is your goal, reducing the choke DCR is only a good option if you can maintain the same or close henry value.
And again I must stress that bumping up the B+ to get a more dynamic or aggressive sounding amp is not a good practice. Most commercial amps were designed at the optimum operating points. Some even beyond that such as Dynaco because tubes were cheap in those days. And remember that line voltage in the 1950/60s was 110-115v. Today we have 120-125v.
You really need to carefully analyse the circuit before raising the B+.
