Short Answer. Yes.

Long Answer, it depends.
Is this a desktop PC or a laptop? If it is a laptop, I would very strongly suggest you do not do this.

If it is a Desktop PC, then it depends on how well the computer is able to handle long time running. A great cooling system is key, if you can be 100% confident that your PC will not overheat while running minecraft and other things on the Pc, then go ahead. Otherwise, I wouldn't.

Also, like TMT said, you can use software instead of physically using your mouse. Not sure about any specific programs though.

You can also do it via software. It's usually called 'click-and-drag' or 'click-and-hold' in various programs. I think it's even included in some iterations of accessibility software.
