EBR's review details suggest the forks and chainstays between our models are identical. I'd go for it. You are already running 20" x 1.95" setup which is less than 1/2 an inch total and only 0.20 of an inch shy either side of 2.40", that's nothing. Don't forget to upsize slightly larger matching inner tubes with tires, to avoid problems.
When my Dolphin's OEM tires wear out, I'm already looking at:
Schwalbe Super Moto-X 20" x 2.40"
OR
Vans by Cult 20" x 2.40" Classic Waffle in Black
I don't have a lot of water-shedding needs to deal with, so the fun and aesthetic of Van waffles might win over practicality.
