Can you still play the old DOS Where in the World is Carmen Sandiego?

yep. DOSBox runs it without much fuss, mount the folder the game is in and launch the exe. the Internet Archive also has DOS versions you can play straight in the browser, search the title there. heads up, the original shipped with a World Almanac in the box and the game leans on it, so without the book you'll be googling capitals and flags a lot. which is kind of the point of it anyway.
