kernel-default-base is kind of minimal version of default kernel, usable in 
certain virtualization setups, for example. 

Actually it looks like in SLE-15-SP3 wireguard.ko is in kernel-default rather 
in -extra. That was case in SP2.

$ rpm -ql kernel-default | ag wireguard.ko
/lib/modules/5.3.18-59.27-default/kernel/drivers/net/wireguard/wireguard.ko.xz

If the module is not present, maybe it is not compiled for s390x. Maybe SUSE’s 
support could enlighten why such choice has been made?
