Yes !
You can do what is done by the BuildPipeline Plugin (https://wiki.jenkins-ci.org/display/JENKINS/Build+Pipeline+Plugin) which propose to display the parameters in a small box above each job. In our case, we should display the parameters of the first Task of the stage.
A better solution is to display a ? (or whatever) beside the round circle to relaunch a step and display the parameters of the Task on mouse over.
I prefer the second solution personnaly for clarity reason.
Moreover, it should be great if we could ahve a button to access directly on the logs of the Job (as done is BuildPipeline).
It is possible to display the parameters of the pipeline by adding some text in the "Customize Task Description Template" of the Start Job. This is only a workaround and cannot substitute to have the parameters displayed in another dedicated box.
