That's the potential difference across the choke limit. You'll be FINE in a CLC filter. Another consideration is the HIPOT rating between winding and core, as the core is usually at chassis ground potential.

"That's the potential difference across the choke limit."
That's not correct. The voltage rating of a choke is the maximum rated continuous DC voltage between the windings and the case. Hi-pot is a stress test intended to detect failures in the production process. It should never be used as a measure of the transformer's voltage rating in normal operation.

For 25 volts over limit I would not worry about it. If the choke is insulated from ground, voltage can go higher. For safety reasons, insulated chokes should be under a chassis with a bottom plate to prevent contact.
