Is the Altera DE2-115 board compatible with this adaptor?

Look on p15 of the DE-115 schematic. It shows the pins that are connected to the HSMC connector. Since the signals are named P/N its highly likely that these pins are connected to LVDS signals on the FPGA. If you look on p23, you will see that the signals are indeed connected to pins that can be configured as LVDS. The high-speed transceiver lanes on the HSMC are not connected.
If the TI board uses the transceiver lanes, then this board would not be useful to you.

Can I be sure of the DE2-115 board compatibility with all TI's ADC EVMs compatible with this adaptor? If not, which aspects should I be careful of to verify compatibility?

Compare the schematics of the TI EVMs to the HSMC specification and to the Altera board.
The LVDS signals on the HSMC can be configured as LVDS or single-ended I/O. If you look on p27 of the schematic, you will see that VCCIO for the HSMC connector can be set using a jumper. If the TI EVM board HSMC connector uses the pins in the LVDS section of the connector, then you need to check whether the FPGA needs to interface using 2.5V LVDS or 1.5/1.8/2.5/3.3V LVCMOS.
If the TI EVM uses the transceivers, then the DE-115 board will not work. If you do need to use a board with transceivers, the DE4 board would probably work for you. Any required AC coupling due to common-mode incompatibilities should be on the EVM. However, you would need to check.
