You can VNC to the RPi. The Pi 2 is much faster and with more RAM then 
the old Pi. It should be ok for using Lazarus.
Even it is slow, you only do the compilation once, after you completely 
finish coding the project on Linux PC. The speed is not an issue.

There is also another option:
You buy a much more powerful ARM computer to do your interactive 
development.
I bought an Odroid U3  from http://www.hardkernel.com a few years ago to 
do my Linux-ARM Lazarus development.
After the project is compiled into a binary executable, I just moved it 
to the RPi to run without any modification or change at all.

Now they have even more powerful ARM embedded computers already and the 
speed should be close to a Windows PC.
