No, there are some differences like:
- rootkit scanning enabled by default in CCE, not in CIS,
- scanning for MBR infections in CCE not in CIS,
- scanning for abnormal system settings in CCE ,not in CIS,
- more aggressive disk access methods in CCE, not in CIS,
- scanning for "bad certificate" files in CCE, not in CIS,
- scanning for infected partitions in CCE, not in CIS,
These are all I am able to think about now..
