Nope. 0'00" is a
separate piece, with the sole instruction "in front of an audience, perform a disciplined action". It can be played in any way by any one, presumably without duration. Sort of. One3 is a piece for amplification in which a halls amplification system is set to the edge of feedback, and the music that occurs is the amplified sound of the hall. It has no specified duration. 0'00" and One3 are successors to 4'33", not the same.
As far as performing 0'00" without duration, it's theoretically possible to sit in front of an audience, do nothing, claim that was a 'disciplined action' and further claim the piece ended as it began... But I think that really violates the intent of it. And really, that's only "music" because that's what one chooses to call it.

except it became 4'33" by john cage. the whole emphasis in the piece IS that the piece takes a certain amount of time, along with showing that music requires participation by the listener. and eventually it got the silly title One3 = 4′33″ (0′00″) + . I still say duration is the only true value all music shares, along with audibility. how does that
differentiate music from a horn blast from a car? it doesn't. and even 4'33" is technically audible. just my two cents.
0'00" by John Cage.
