Hello,
According to the user manual of the dock [1]:
You can do some further tests with the network manager, if you wish.
You can dump the network configuration (as seen by the Network Manager) for both original and cloned Debian machines with the following command, replacing CONNECTION_NAME with the ethernet connection name listed by the first of the two commands:A further test could be done collecting the output of previous commands from a third Debian computer, different from the first two.
Some other logs could be collected before and after powering off/turning on the docking station.

According to the user manual of the dock [1]:
I don't know if your cloned Debian machine is a "supported machine". If not, the MAC address of the dock may not be the MAC address of the network interface configured by the Debian machine on which you are experiencing the problem. So for unsupported computers, the Lenovo documentation does not clarify which MAC address is sent to the dhcp server to request a dhcp lease.Using the Ethernet connector
The Ethernet connector has two network status indicators. When the green indicator is on, the computer is
connected to a LAN. When the yellow indicator blinks, data is being transmitted.
The following functions are available on supported computers when the dock is connected to both the
computer and the LAN. For the supported computer information, refer to the document Network function
support – Option Compatibility Matrix available at www.lenovo.com/accessoriesguide
