Hi,
You can take the exam, however, if you want to earn Microsoft 365 Certified: Administrator Expert certification you will need to have at least one of the 5 prerequisite certifications in addition to passing MS-102.
For additional questions relating to exam/certifications please ask your question in the Microsoft Certification forum using link below. There are dedicated support moderators over there that will respond to your question in 1 business day:
