Well the cord is generally attributed to etheric projection where you, how to put this, let your astral body take over all functions of the physical body, the etheric matter is passed via a cord from the physcial body into the energy body. So maybe perhaps.
As for normal astral i think not, you might come round feeling like you've done several rounds with a boxer and you might need to re center and balance yourself but i do not think so in that case as your physical body is still breathing and still alive.

It is absolutely possible to die when astral projecting. It is extremely rare but happens.
Actually the thing between astral projection and etheric projection is what Allegra suggested with the subtle body taking over all functions of the physical body becoming the etheric body, but also the chord attaching the astral body with the physical is broken during etheric projecting after the etheric body takes over all functions (which is why etheric projecting takes time and can be very dangerous).
