If you can locate a factory manual, it's do-able. Without that, you won't where to set the cams in relation to the gears, and you'll bend valve stems.

Is it really that bad? Is the chain slapping the cases or is it loose enough to jump a tooth?

Not to be mean, but the old Honda 400 twin in it's various iterations was a bargain basement bike and not the best Honda quality. It was designed to give 50 or 60 thousand miles of reliable service and then be discarded. Your problem is that the chain is stretched out. It will need a new chain which means a complete dismantling of the engine, since the cam chain runs between the cylinders. You can do it with a manual if you have the tools and have some aptitude for that kind of work. I'm not sure how many special tools you will need. If you decide to do it you need to check out the parts availability first. The may be no more chains or tensioners or other critical left after all these years.

I'd just ride it until it fails which, if that noise is the chain knocking against the engine case, won't be long.

Most are NOT adjustable by "just tightening a nut".

On some, you actually loosen a bolt to allow the spring inside to take up additional tension and then snug the bolt, and lock nut, back down again.

Be sure you have the right proceedure before you move on to the next step.

P.S. What makes you so sure that is what is causing the noise ?
Just because somebody on the Internet suggested it ??
A loose cam chain usually has a pretty distinctive noise.......for anyone with experience who is actually THERE to hear it.
