Can a 7.62x39mm round be safely fired from 30-06 rifle?

The 7.62x39mm cartridge is significantly shorter than the 30-06 cartridge. If a 7.62x39mm round is loaded into a 30-06 chamber, there will be a large amount of empty space in the chamber.

When the round is fired, the primer will ignite the propellant, and the expanding gases will push the bullet forward. However, because there is so much empty space in the chamber, the bullet will not be able to build up enough pressure to properly stabilize itself. This can cause the bullet to tumble in flight, which can lead to inaccuracy and potential injury to the shooter.

Additionally, the 30-06 rifle has a longer barrel than a 7.62x39mm rifle. This means that the 7.62x39mm bullet will not have enough time to fully burn its propellant before it exits the barrel. This can result in unburned powder residue, which can foul the rifle and cause it to malfunction.
