No, there's a serial connection exposed on the PCB, which outputs the U-Boot shell and kernel boot messages.
I made a little hack (3-pin female header soldered to the board and hole in hte back cover) so I don't have to open the kobo to connect to the serial port.
The thing is that Kobo's uboot has a boot delay of zero so you can't get into the shell.
I hope the boot delay is configured in uboot's attributes and I can modify it with a hex editor.
