Yes, paste the code into notepad, edit it so that it's right for your environment, and save it as a .bat or .cmd file. Make sure the path to the executable is the same as on your computer, and likewise for the .dtsx file. If your package is stored in msdb instead of the file system, you'll have to tweak the command a bit - just search for the syntax for dtexec.exe to find out how to do that.
