Just try it on analogue DC; it will either work or not - if it doesn't then you won't have damaged anything, but if it works fine, then you're good to go! 
The only reason to pull a decoder out would be if you were on a very tight budget and wanted to re-sell the decoder, but in most cases that really wouldn't be worth doing and (as Alan mentions) might well require a lot of hassle re-wiring lights, smoke etc.

since it has been determined it is a Digitrax DG583, it has, as most DCC decoders have, a DC mode.
You can leave it in. The locomotive will take a higher DC voltage to get running than your straight DC locos.

In which case the decoder setting may need changing or you may choose your original plan and remove the decoder. If you opt for the latter you'll need to reinstall the DC jumper PC board, and alter the relevant switches. If the installation has some degree of customisation this may also need attention.

If I remember correctly the standard socket only supports the front/rear lights and possibly smoke function on only one of the arrays of pins. Bachmann may have extended it to support some more functions on the 2nd array of pins.
When I fitted a DG583AR in mine I used the additional plug/socket on the side of the decoder to drive all the lights including the firebox lights etc. The lighting wires all connect to the existing Bachmann main board via header plugs, so I disconnected them from the main board and made a little adapter board between the Bachmann wiring and the decoder, with appropriate resistors.
As Neil says, if you want to revert to DC you'll need the original DC jumper board to replace the decoder. If it's missing you may be able to get one from Bachmann or from someone who doesn't need theirs. (At which point I have to say sorry I need to keep mine!) If I remember correctly, the 2-6-6-2 also came with another adapter board with wiring to allow you to connect to a non- plug-n-play decoder.
[edit]
According to the instructions, one of the switches on the main board controls whether the cab light and firebox are under DC or DCC control. I suspect this either links the lights to the main board voltage regulator or to pins on the decoder socket (but not sure which functions)

and now you can sell your decoder for a bit of cash
