Please do not post hypothetical questions assuming something in the future.
A Bank guarantee can not be transferred as it is not a negotiable instrument and it is indemnity.
However, if one company is willing, they may return original BG to you with such discharge letter, and you may have to obtain another guarantee in the name of a new employer through a fresh guarantee.
