it is possible to add arbitrary custom resolutions using the
vboxcontrol.exe (from the guest additions):
vboxcontrol addcustommode <width> <height> <bpp>
This mode will then be available in the "Adjust Resolution" dialog.
Also you could try to set an arbitrary high resolution mode either from
vboxcontrol setvideomode <width> <height> <bpp> <screen>
where screen = 0 is the primary display.
Or from the host using the VBoxManage controlvm setvideomodehint command.
