my vintage macbook pro wont finish start up so can i start it or repair it using my macbook

I have a MacBook Pro built March 2010 that has been working reasonably well until the other day when all the applications I had running on it kept crashing. I saw the spinning beach ball more and more until it became impossible to work on it at all. The MBP had thrown me several panic kernel attacks up to this point but I couldn't through lack of understanding on my part to interpret console data, work out what the problem was. The expensive "Techtool Pro" software I have installed didn't alert me to anything either, much to my annoyance!

so I had to force quit using the start up button as all software had 'Frozen'.

when I came to switch the MBP on again the start up screen took ages for the bar under the apple logo to fill up - maybe 15 minutes. It has not moved on from there! It is charging its battery, but I'm stuck now not knowing what to do. I believe it may be a hardware failure at worst but can I boot it aomehow using my much newer MacBook? Anyone got any ideas how I can mend it o r get the data safely wiped off for security if it can't be salvaged?

Please reply to this damsel in distress! Thanks everyone. 😱

P.s. Using the latest Mac OS software.
