The only times it may cause a problem is if something like /opt/bin has hard links to things in /opt/app. This is unlikely, as most links being created now are symbolic links - in which case it shouldn't be an issue.
Sometimes you may need to set security labels when setting things up - the easiest is to "resorecon -r /opt" or "restorecon -r /opt/app" after getting the mount working and files loaded.
