For sure. Back when I messed with electronics I was working on a TV, trying to locate a "mechanical" fault and bridge it, when I dropped a screwdriver and accidentally flash discharged a very large capacitor, which went off like a bomb. Scratch one TV, and 3 days in the hospital - an 8 inch screwdiver explosively driven through your abdomen is unpleasant. I got lucky, at that - it didn't perforate any organs (how, I've no clue).
For that matter, there is a hand grenade design that uses a "super-capacitor" with a winding of osmium wire around it, inside a fragmentation casing. Pull the pin, a delay circuit gives you a 4 second delay once you throw it, then the capacitor discharges through the osmium coil, vaporizing it and blowing the grenade to little high speed lethal bits of shrapnel.
