Any harm if i remove the "Company Administrator" from our site collection administrator

Hi all,

I want to start a new sharepoint project and i am planning to work on the classic team site root site collection. now i checked the "Site collection Administrator" for the root site collection, and i found that the "Company Administrator" is already defined, as follow:-

where i checked who is defined inside the "Company Administrator" using this command:-

Import-Module MSOnline
Connect-MsolService

$role = Get-MsolRole -RoleName "Company Administrator"
Get-MsolRoleMember -RoleObjectId $role.ObjectId | Export -CSV c:\CompanyAdministrator.csv

and i found that this group contain 4 users; the office 365 admin + 3 manager end users.

now i want to remove the "Company Administrator" from being defined inside the "Site Collection administrator", and i want to only add the office 365 admin.. but my question if this is a supported operation? now i know that technically any "company administrator" can add him self as a "site collection administrator", but i do not want this to happen by defualt on the new site collection.
