Its unlikely to be possible, and if it is possible its not going to be cheap or easy.
PC104+ is essentially a PCI interface and the biggest problem you'll have is finding a laptop which exposes a PCI interface to the outside world.
If your laptop has a CardBus slot then you're off to a bit of a start, since this is another flavor of PCI (the CardBus controller is essentially a PCI bridge) so its theoretically possible that someone has made a CardBus to PC104+ bridge device - but the demand for such a thing would be so low that even if it does exist it would be astronomically expensive.
Another option would be if your laptop has a dedicated docking station (a 'real' docking station, not a USB port-expander), and if this docking station contains at least 1 PCI slot.
You could then plug a PCI-PC104+ adapter into the docking station and dock the laptop there.
Unfortunately these 'real' docking stations seem to have been becoming more and more scarce for a number of years already for a number of reasons so it unlikely that you're going to find this option either.
So although its possibly technically do-able I don't think its likely that its going to be economically or practically possible ... sorry ...
