NO
Enantiomers are only nonsuperimposable mirror images.
Butane and xylene are nonsuperimposable non-mirror images, and they are not enantiomers.

It may be that on rotating part of one they will be mirror images

If a pair of stereoisomers  are non-superimposable mirror images of each other, then they are enantiomers.

Enantiomers also must have a minimum of 1 chiral carbon (a carbon with 4 differerent substituents attached).  If there is no chiral carbon, it's not an enantiomer.
