Most enterprise PCs are Windows machines and integrate with Microsoft services easily. The only way Microsoft is going to lose the enterprise market is if enterprise PCs move away from Windows.
But, for enterprises, the only reasonable migration away from Windows is Mac. JAMF Pro for Mac can be hosted on-premise on Linux. The majority of enterprise software runs on Mac. However, Macs are expensive so it's unlikely to overtake Windows enterprise machine usage.
Hardware support for Linux PCs is poor and lacks the manageable of Windows PCs with Active Directory and GPO, or JAMF for Macs. Enterprise software usually doesn't support Linux. Linux PCs are uncommon for personal use and corporations don't want to train users how to use Linux.
