Yes, you are able to use your current world. Just use the command line to point to the world file, something like I have for my world:

valheim_server -nographics -batchmode -name "Veizlaheimr" -port 2456 -world "Veizlaheimr" -password "*******" -crossplay -savedir "D:\Dedicated Server\Valheim\Veizlaheimr\Worlds"
