Not entirely sure if it's safe, though I didn't encounter any obvious problems running it. The reason for that change was to get rid of a memory alignment issue on the ARM boards we used.
IIRC `lwm2m_data_type_t` is an enum and apparently enums can have strange widths, so all the following struct members got misaligned, leading to hard faults. Making the enum member the last one fixed that for us.
