According to a report by German news site WinFuture, Microsoft's new Surface 4 Laptop—set to debut this April—will offer AMD and Intel processor options side by side.

With 2020's Surface Laptop 3, only the larger 15-inch model got an AMD option—the smaller 13.5-inch version was Intel-only. But this year with Surface Laptop 4, WinFuture says that Ryzen 5 4680U and Ryzen 7 4980U "Surface Edition" CPUs—lightly modified for Microsoft's tight vertical integration—will be available in the smaller 13.5-inch Surface laptops as well.
