I doubt that,
Cat converters are killed by sulfur and other metals/nonmetals... but start the car by pushing shouldn't do it. Me guesses it has to do more with all the electronics that are found inside engines these days....
I learned the hard way (by helping a friend in dire need) that you can;t just change the battery of the car anymore, have to take it to the dealer! They have to "reset" the onboard computer, otherwise power windows and central lock stopped working :ROFL"
