Easily - if the intended application is in space, or in some sealed
location, or underwater, or any place a large amount of air is not
easily available. Which, granted, does limit things a bit...

(You know, I wonder if a simple high-pressure carbon dioxide grenade
might make a viable anti-combustion-engine weapon, if it could remove or
at least heavily dilute oxygen in the area for long enough to stall the
engine.)
