Yes, I've made dealers remove it before I would sign the final papers and drive off the lot.
That said, most dealers these days use vinyl transfers which can easily be removed by heating with a hair dryer or heat gun and then carefully peeled using a soft plastic scraper or a finger nail. Any remaining residue can be removed with "Goo-Gone" or similar and then washed.
