Seemingly not. Seemingly either dkms needs to build the kernel
modules or a package needs to provide the modules that fit to your
kernel, as well as to your virtualbox version and then those kernel
modules needs to be loaded.

I installed virtualbox from the Oracle website (not from the distro's
repositories) on Arch Linux. Assuming the modules are not
provided by a package, then the commands to check against a version
mismatch are the same for Ubuntu:

[rocketmouse at archlinux ~]$ VirtualBox --help | head -1
Oracle VM VirtualBox Manager 5.2.16
[rocketmouse at archlinux ~]$ uname -r
4.16.18-rt11-1-rt
