That was a little more accurate than the claim Pizza Express is keeping halal "secret", but it downplayed one important element.

You'd have had to read half way down to discover the company's statement on halal food, which pointed out that its policy on this hasn't changed since 2007:

"Due to the growing popularity of the SUBWAY® chain, with the diverse multicultural population across the UK and Ireland, we put a programme in place in 2007 to ensure that the population demographic is taken into account when new store openings are considered in order that we meet consumer demand in each location.

All our suppliers comply with EU animal welfare legislation as a minimum and we require suppliers of Halal products to adopt the stunning of animals prior to their slaughter. All Halal meats are certified by the appropriate Halal authorities.

All Halal SUBWAY® stores have numerous signs stating that they serve Halal food. These are situated on the menu panels, nutritional information and in the front window of the store."

While the company hasn't commented on which stores have removed ham and bacon from their menus (and there do appear to be a couple), there's been no sudden change in policy from the food chain.
