Older OS on a new Mac? Can I run OS 10.6.8 on one of the newest Macs?

Your last question is kind of backwards. It should really be: "Does 10.6.8 support the components and subsystems of the new machines?" The answer is that it almost certainly will not work on the MBP Retina. Better odds on the "traditional" model but still iffy.

If it's a retina display, you're 99.99999% certain out of luck. No OS prior to the one that ships with those computers will support those displays.
If it's a non-retina MBP it MAY work, though it also may not. In theory, you can't do it. You can try this: do a full backup of the disk from your older MBP onto an external drive, start up the new one, switch the new MBP to use that external drive as its startup disk, restart from that external drive, do a full backup of the startup (external) drive to its internal drive and reset the new MBP to start up from its internal drive. Be sure to also do a complete backup of the new computer first, in case this doesn't work, or at least be sure you have everything you need to do a clean re-install of the system.

My time is limited, precious. I tend not to waste it checking every upgrade that shows up fixing this and that, after I consider the version I run is stable and fulfills my needs. I don't have the urgent need to check MacUpdate or VersionTracker every day. I come from a vintage era when I punched FORTRAN IV code into cards, then into an IBM 1180 mainframe feeder to be compiled into a tape that was run once a day. I've been trying to stay abreast of Cybernetics but have yet to embrace iOS because of deeply engrained habits. I adopted the Mac mouse and GUI immediately in 1984, but have yet to feel comfortable with iOS fingers on a trackPad (the latest trend).
My sweet wife (born and raised in Illinois) jumped into Lion as soon as it came out, and I had to help her struggle with the transition from Snow Leopard. She reminds me it's good business savvy for Apple to push the envelope, to 'improve' even when what we have still works (people who design and develop these improved systems need a job, the economy needs them). Evolution is a force I respect, but I choose not to spend too much of my time in endeavors that keep me from addressing my urgent priorities. I don't apologize for wanting to hold on to tried-and-trusty and expressing concern when what I have been depending on runs of hardware that may be obsolete and therefore unavailable when my machines break down with no emulators available to rescue me.
