No

refer the constraints while creating NIC in Azure

Constraints A VM must have at least one network interface attached to it.

A VM can only have as many network interfaces attached to it as the VM size supports. To learn more about how many network interfaces each VM size supports, see Sizes for virtual machines in Azure. All sizes support at least two network interfaces.

The network interfaces you add to a VM can't currently be attached to another VM.

The answer is YES! Definitely, multiple VMs can use a single Network Interface Card---- BUT ONLY ONE VM AT A TIME. Azure allows you to create a NIC as a separate entity. So, at one time, it can be attached to only one VM. But you can, at any time as per your business requirement, detach and assign it to any other VM.

In the new Resource Group model, you can create a NIC as an atomic, region based, entity. You can then assign and unassign that Nic to a VM at will. So if you want to retain the MAC address of a specific Nic across a number of VMs that is possible. However you can only use a Nic in one VM at a time.
