Cant see any other posts that are sorta the same as this so here goes, i have made a simple electric chair prop that uses a 12v timer cycle relay board to stop and start bits and pieces of the prop, i was wondering if its possible to link the timer to an older style single push button hard wired remote that i have for a fog machine that doesnt get used much anymore

So in short i want the cycle timer to open its circuit, do its bit with the chair, and activate the fog machine (which is always hot at the mains, awaiting signal from remote)

Yes, easily done with a RELAY board, but not with the one you linked to, that uses MOSFETS. Open the remote and connect the dry contacts of the relay to the wires going to the push button of the remote. The relay will function as the push button. One thing to keep in mind though, it's not 100% reliable because it depends on the heating cycles of the fog machine. If it's in a re-heat cycle when the controller closes the relay, you won't get any fog. For the most part, it works pretty well. Also, be sure to isolate the relay board and connections.

Yes. You should have room inside the remote case for a small relay.

The link you provided for the timer module is only single output, so it can only control one function of your prop unless you want the fog machine to run the same amount of time as the chair. Here's a link to the type of relay you'll need for the fogger. This one operates on 12vdc, you'll need to get one that matches whatever voltage you are using for the timer module. The two wires from the remote push button will go to the "C" and "N.O." pins of the relay. Neg and Pos power to the coil of the relay comes from the outputs of the timer. As I mentioned, this will only work when the "ready" light is lit on the remote.

No worries on the double thread. Here's a diagram of the relay pinouts. The two wires from the remote button go to pins 3 (COM) & 5 (NO). Pos and neg power to energize the relay coil when you want fog go to pins 1 & 2.
