I would say that for some world's *yes* it's possible.

Take world 1-4 from the first Super Mario Bros game.  Here is [a video](https://youtu.be/WFD-VAJDriY) of a near exact replica (with a few differences in textures and the floating bridge above Bowser at the end is longer than the originals) with the level ID in the description.  For comparison, here is [a video of the original game](https://youtu.be/GfroW2zfMH0).

There is also a [Reddit](https://www.reddit.com/r/MarioMaker/comments/3y34xi/super_mario_bros_11_12/) for world's 1-1 and 1-2.  They provide the level ID's, but whether or not they are exact I'm not sure since I can't play them.  It's mentioned that they are as close as possible to the originals with the exception of the limitations imposed in Super Mario Maker.
