I guess Embraer means bus arrival, which should deposit you at the head of B gates. The LAX flight will likely depart from C gates.
Technically that's a terminal change but at CPH the Terminals are just different areas of one big terminal. No security but maybe 5 min walk from B to C where you go through exit passport control, then 1-5 minutes to the actual gate.
Well, bus gates is always a risk at CPH. But if there isn't a bus gate, I'd say that an E195 + long haul risks being the longest possible walk at CPH: arrival at A-gates and departure from E-gates. Surely E-gates is the most common for SAS long haul since quite some time? It's still doable and could take something like 15 min if there is little or no queue in passport control. For long haul flights with one departure per day, SAS will most likely monitor the number of connecting passengers that haven't showed up at the gate, and they know approximately when to expect passengers who just made the connection. So you're very unlikely to misconnect by a few minutes due to a slightly late incoming flight or 10 min extra delay in passport control.
