I want to block up a basement window. It is below a deck and is of no
use.

My question is should I remove the window or take it out?

Yes. Wait, no.

OK, I know what you mean.

There is no real reason to remove it unless it is wood frame and rotted.
Just make a frame for the inside with insulation and cover it. Depending on
accessibility, you can do the same for the outside. If you leave it in,
some day if the window is needed, it will be there.
