Will a HDMI coupler like the one below work like a normal HDMI cable?

Yup, these are passive "pass through" devices, so the only thing you need to be careful of is matching up the genders. The adaptor you've shown is Female-Female, so can be used to join together 2 regular HDMI cables (which are always Male-Male) to make a longer cable; but can't be plugged directly into the Raspberry Pi (which has a Female HDMI connector).
