If I add the following to
router bgp 65004
adding this>>> network 10.1.23.0 mask 255.255.255.0
Will it cause any notwork disruption or cause BGP to re-converge?

It shouldn't cause your BGP sessions to reestablish or reconverge. It should only cause BGP to begin announcing 10.1.23.0/24 to BGP peers as long as this route is in your route-table learned from an IGP or as a connected or static route. 'show ip bgp' will reveal if it's in the bgp table.

It is not in the BGP table. I will also be adding the following..... ip route 10.1.23.0 255.255.255.0 GigabitEthernet0/0

You'll be good to go then. Once the static route and the BGP network statement are in you can do a 'soft' reset to propagate the route quicker; or just wait.
clear ip bgp * soft
This wont cause any service disruption. confirm the route is in the route-table, then confirm it's in the BGP table. In order to confirm it's getting to a particular BGP peer use the following:
show ip bgp neighbors x.x.x.x advertised-routes

Thanks for your help. Thought it would be fine but I don't do that much with routing and I wanted to be sure.
