It's something you
can do, but not something you'll be able to
succeed at. At least not on your first playthrough.
There will be tons of guardians and hard enemies on the way, you won't have enough energy or powerful weapons (which break btw) to defeat even your first enemy.
I'm sure there will be speedrunners that will do it, and I'm sure that as you play the game and find its secrets you'll be able to start a new game, and know where to find some powerful weapon and buy potions that will allow you to beat Ganon right from the start. But that's something you'll be able to do after knowing the map and where everything is.
So unless you first watch a playthrough or read a walkthrough to find where to get the best equipment, you will absolutely NOT reach Ganon on your first try.

Look at the top-left as soon as the screen fades to black. Those sneaky bastards had it right in our noses and we never noticed due to the fadeout.
