The TFTP request from alix asks for a binary transfer
As a comparison, the reaction against the RRQ from the linux box:
12:38:12.807419 kubuntu-neu.fritz.box.36672 > alix.fritz.box.tftp: 19
RRQ "pxeboot" (DF)

The TFTP request from your linux box asks for an ascii transfer
There is a difference between the 2 tftp transfers that may explain your
problem
Can you try the cli tftp and type "binary" before "get pxeboot" ?
like the following :
tftp 192.168.0.44
tftp> binary
tftp> get pxeboot
