I have now been able to validate the Live Fedora CD by booting it on an older machine. The Lenovo C540 does not boot with it though. Thanks to Chris Murphy's suggestions I also got a bootable USB stick.
The Lenovo picks up some of the boot code and comes to a menu where i can choose "Start Live CD", "Verify media and start live CD" and "Troubleshoot". Selecting "start live CD" the machine shows a black screen with a blinking cursor at the top left and freezes. The keyboard NumLock/CapsLock LEDs stop responding to toggle. Ctrl-Alt-Del work when frozen. I could not find Lenovo firmware updates to flash the BIOS. I initially installed Fedora 20 on the Lenovo C540 and I remember the installation media used to work okay on it.
