Yes and no.
The T20 doesn't seem to have iDRAC (IPMI) support, so BIOS/UEFI
is not available through a serial console.
The first time you have an opportunity for a serial console is in GRUB;
then again you have an opportunity for the kernel output; then finally
you can have a login on a serial terminal.
You will need a USB to RS232 serial adapter, and then an appropriate
cable to talk to your terminal device. The other end can also be a USB
to RS232 serial adapter. In between you might have a 9 pin
serial cable or a specially wired RJ45 (looks like ethernet)
cable.
The name of the device should be something like /dev/ttyS0
(S1,S2,S3...) or can be /dev/ttyUSB0. USB ports can be renumbered on
each boot, but as long as there is only one serial adapter connected,
it should always be recognized as /dev/ttyUSB0
