Is it okay to bend the output electrolytic filter capacitor right next to my SMPS inductor?
It looks like you have a high voltage buck converter here. This layout looks good by eye to me, as long as you have a solid ground connection.
If you're soldering these by hand and the capacitor isn't physically compromised by this, it should work just fine electrically. You have ceramic bypass caps locally, and the low ESR/ESL of those should meet loop stability and inductive ringing under control, as long as they are chosen correctly. The electrolytic capacitor is basically just to store more charge as a reservoir, so its placement on the board is not as critical.
Also note that for a buck, the input capacitor is the most critical in terms of board layout, since it's the input current that is discontinuous (trapezoidal wave with hard edges), while I(out) is the same as inductor current (triangle wave).
