Yes but if all you want is to preserve the serial number for future reference it beats a magic marker. Or, if its just looks you care about you can buy a complete tower assembly with the nice tag already mounted with original rivets. (Like so many others have done.) A 420 tower might be a little hard to find. I'm being a bit facetious here but its true. Those tags move around like used hour meters. And if you did find a reproduction you could put any number you like on it. I have seen a few held on with pop rivets which is a dead give away. Usually for painting purposes I hope but who knows? There certainly isn't much to be gained by putting a newer S/N number on these machines. At least a Deere duplicate would show a little honesty to a future buyer.The ones that you could get from John Deere were hard to get and had the word "DUPLICATE" on it. I did not like that.
