Kew Bridge station has very few people using it during the day so any thief that spots your bike will have plenty of time to work on it undisturbed.
If it is a cheaper bike you wouldn't mind losing, then possible locations heading from Kew Bridge to Chiswick roundabout are - a lamp post by the cafe/corner shop/fried chicken place on the other side of the road from the station, the bike racks in front of Brentford leisure centre and possibly the petrol station at Chiswick roundabout although I don't think there are any bike racks there.
The Brompton factory is just around the corner from Kew Bridge so maybe they have secure bike parking (but maybe it is just for Bromptons)
Another possible option could be to leave the bike at Chiswick Business Park. This is about 10 mins walk from Kew Bridge but just across the road from Gunnersbury station on the District line / London Overground. I don't know what the secure bike parking facilities are in the business park but there are some pretty big companies there so there may be something. There are bike racks in front of the gym and, I think, Starbucks, in the business park.
I used to commute to Canary Wharf from Kew Bridge via Waterloo and preferred that route over the District line although the District line was a useful plan B in case of problems with SW Trains. You needed to get a train before around 7:30am to be pretty sure of a seat, and the District line is similar. Waterloo to Canary Wharf is a crush.
I use a very old MTB for getting around the area and in the last 10 years I've only had two things stolen (a wheel and seat + seat post) and both times this was outside a quiet pub in the evening. However, I have only left my bike for a few hours at the most, not all day.
