Is it safe to remove dated bathroom tile borders by picking them out fr the in-between grout n replace w new?

I intend to keep the surrounding bathroom tiles as they are in perfect color and condition. Painting over them is another option which is neither easy and I thought replacing them with new (i.e. small square glass tiles) will give the bathroom a very interesting lift.|||yes, cut the grout and chissel out the tile. note: use duct tape over other tiles to prevent accidential damage|||DOUBT IT YOULL CHIP THE OTHERS
