Yes, you should be able to execute any tool in the Geoprocessing toolbox like that. I've always used the syntax used in the "Executing a system tool with managed assembly" section.
However, I'm surprised that the GPXToFeature tool isn't in the ArcObjects API reference (like this one for FeatureToRaster). Then again, none of the toolboxes after DataManagementTools are showing up, either.

Do you know of either a filter that I could use the GxDialog to allow the user to navigate to the GPX (rather than the alternative of them manually finding the path and giving it to the program through a textbox), or a different dialog window entirely? Essentially what I would like is to allow the dialog window from selecting the GPX file as if the user was running the actual tool.
