Yes, they both have the same meaning and can be used interchangeably. Both here mean to take it easy and do something calm or enjoyable without any worries or stress. Ex: I want to go home and relax. = I want to go home and chill out. Ex: I can finally relax after a hard day of work. = I can finally chill out after a hard day of work.
