Yes. That's okay, but . . .


But to be correct, you should put a hyphen between "4" and "hour":

It's a 4-hour stopover.

And it's more formal to use the word "four":

It's a four-hour stopover.

The hyphen is because both "four" and "hour" are working together to modify "stopover".

What kind of stopover is it? A four-hour stopover.

The same is true whenever a two-word combination functions as a single adjective to modify a noun:

She's a well-behaved child. (What kind of child?)
He was hell-bent on getting it done. (What was he?)
