In technical terms, no as long as creatures have some way to sustain itself. Say if undead were brought back using electrical impulses with an intact nervous system, they don't need a heart. You could remove the whole chest and it would still be alive. Though Grimm tend to stay dead when inflicted with a severe injury.
