Is it dangerous to take out tampon with hymn?

I assume that you mean hymen, if so then no it's not dangerous to remove a tampon with a hymen. The vast majority of women have a hymen, if the hymen covers more of the vaginal opening then you simply need to push the hymen out of the way so you can easily remove the tampon. For the most part the hymen shouldn't be an issue when using tampons.
