The only thing we have to go on is the statement from (ISC)². Read it for what it is and try not to read to much into it.
"You can substitute a maximum of one year work experience if you hold a four-year college degree...". Since the statement does not mention a particular course of study, it is reasonable to presume that any course will do.
"...or regional equivalent..." indicates that they understand that the degree may come from different parts of the world and may have a slightly different name.
That said, definitive answers come only from the endorsements team and the only way to get a question in front of them is to submit it as an endorsement request. In the unlikely event of a problem, they will let you know and you will have a chance to defend your position.
Also, keep in mind that 5 is a lower-limit. If you can, submit more. Then if something is denied it will not even come up as an issue as long as the approved total is at least 5. You will encounter this same concern with CPEs, and the trick is the same... doing more than the minimum insulates you from worrying about the minutia.
